IEVERWI-N E, OF NEWARK, NEW JERSEY ATTACHMENE EUR INTERNAL COMBUSTION ENGINES Application filed December 31, 1929.

The present invention relates to improvements in attachments for internal combustion engines and has reference more particularly v to a means for additionally supplying air to the-intake manifold whereby to increase the efiiciency in the operation-of the engines and glso tend to eliminate the accumulation of car- A further and important object of the in- 1 vent-ion is to provide an attachment [of the above mentioned character whereinair is admitted to a vacuum container within which is arranged achemical ly treated .piece'o'f cotr ton, theoair being caused to be forced through the cotton and to become admixed with the chemical, the chemically treated air being discharged through an outlet, a nipple for delivery to the intake maniitold \of the engine, Where the same comingles with the charge entering .theunanifold Qfrom the carburetor.

Another important object of the invention resides in the provision of anattachment of the above mentioned character that includes a balanced valve for association with the outlet nipple of the container .so that only the atomized air will be discharged from the container .:and.an y overflow will .he eliminated by .the valve in .case .too great an air suction occurs.

Another object is to provide an attachment of the above mentioned character. that can be u eadilyand easily installed without necessitating any material alteration, the same beinga-tall times positive and efficient in its operation-as well as simple in construction, inexpensive, strong and durable.

Other objects and advantages of the in- .vention will become apparent from the following description when 'taken in 1 connection with the accompanying drawings.

.In the drawings wherein 5for the purpose of illustration is shown a preferred embodiment of ,my invention, the numeral 1 designates generally my improved auxiliary air supply attachment, the same comprising .a

cylindrical glass jar 2 that is open at its upper end, the .same decreasing gradually in diameter toward its lower end and the .bottom ,of this glass :jar is formed witha depression 3 tor a purpose to be presently described. A metallic cover a is provided for the open upper end of the glass .jar2 and the bottom face .of this cover is vformed with ,an annular groove within which is seateda (rubher gasket 5 foroefiectingia seal between the cover and the jar '2. For the purpose vof tightly securing the cover on the top of the glass jar, there is provided the .rods 6, the same being disposed radially from a hub 7 and being directed upwardly for disposition adjacent the glass jar 2t Thenpper free'ends of these rodsare directed inwardly for disposition within suitahle aapertured ears 8 formed on itheitop of :the cover 4. The hub 7 is formed with a vertical threaded bore'9 to accommodate the threaded lower end of a jack screw 10, the same being formed at its upper-end with ahead '11 that engages within the depression '3 formed in the bottom of the glass jar2. Byactuating the jack screw 10 "in one direction, 'a downward pressure will be exerted upon the hub 7 and the rods 6 associated therewith and said rods will cooperate with the cover 4 to force the same tightly in engagement with the-upper edge of the jar 2 as obvious from the construction disclosed in the drawings.

An arm 12 extends laterally from the edge of the cover 4 and the outer end of this hori- 5 zontally disposed arm 12 is adapted to be secured on a supporting bracket 13 that is attached to the dash board A whereby the auxiliary air supply device embodying my invention will be properly mounted on the automobile, the securing means for the arm 12 being shown at 14 in Figures 1, 3 and 4. This construction provides the means whereby the device can be readily and easily attached or removed whenever necessary.

Extending through the cover 4 is an air supply pipe 15, the upper end thereof being formed with an air inlet opening 16 and cooperating with this air inlet opening 16 is a needle valve17 for regulating the admission of air to the pipe 15. The lower end portion of the pipe is adapted for disposition within the glass jar 2 and terminates at its lower extremity in the upwardly disposed portion 17 and said upwardly disposed portion 17 is formed with an air distributor head 18. ,This air distributor head includes a series of upwardly pointed teeth 19, the

apex portions of which are formed with openings to permit the air to pass therethrough. The teeth 19 constitute a meansfor retaining the chemically treated cotton 20 that is placed in the glass jar 2 as suggested very clearly in Figure 4. The absorbent material is saturated with a specially formulated non-oily chemical solution known as carbo-vac and consisting of zinc oxide, pickris acid, and a combination of alcohol and gasoline as a base. The air passing clownwardly in the pipe 15 will be discharged through this absorbent material. and will become admixed with vapors rising from the solution to create oxygen gas in the vacuum jar 2. This gas is similar to gas generated when charging a storage battery and when mixed with the charge entering the intake manifold of an engine from the carburetor serves to prevent carbon forming in cylinders of the engine.

The cover 4 is formed with a centrally located outlet opening within which is secured the lower end of the vertical portion of the angular discharge nipple 21 and connected to the discharge end of this nipple is one end of a tube 22, the other end of which 55 enters the intake manifold B of an internal combustion engine C as at 23 with reference more particularly to Figure 1.

Arranged for vertical movement within the vertical portion'of the discharge nipple 21 60 is the balanced valve 24 carried by the upper end of a valve stem 25 that extends downwardly into the glass ar 2. A float 26 is carried by the lower end of this stem 25 while a valve disk 27 is mounted upon the interme- 65 diate portion of the valve stem for coopera tion with the valve seat 28 formed at the lower end of the opening in the cover 4 within which said discharge nipple 21 is secured.

If too much chemical is poured into the glass jar and rises above the wad of cotton, jolting caused by vibrations of the engine or due to an automobile traveling over a rough road would be liable to cause the liquid to splash upwardly and enter the outlet. This would be objectionable but is prevented due to the fact that the float will rise with the liquid and the valve 27 will temporarily close the outlet. It will thus be seen that the valve and its float act as a check valve to prevent liquid entering the outlet. The valve also acts as a check valve when increased speed of the motor creates an increase intake of chemically treated air and as the float valve is above the cotton and its float left upon the surface of liquid which over-saturates the cotton it prevents the cotton from being sucked-up over the float valve and lodging in the nipple 21.

As heretofore stated, by securing the cover tightly upon the upper edge of the glass jar 2, a vacuum will be created in the glass jar and when the air mixes with the fumes from the saturated piece of cotton, an oxygen gas will be formed and this gas will be discharged from the container 2 into the intake manifold through the tube 22 for admixture with the charge entering the manifold from the carburetor D.

The provision of an auxiliary air supply attachment of the above mentioned character will tend to decrease the accumulation of car- 100 bon and to increase theefliciency in the operation of the engine. Furthermore, the simplicity of my device is such as to permit the same to be readily and easily assembled or disassembled for cleaning purposes and the device 105 can be mounted on an automobile without necessitating any material alterations.

l/Vhile I have shown a preferred embodiment of my invention, it is to be understood that minor changes in the size, shape and ar- 110 rangement of parts may be resorted to without departing from the spirit of the inven tion and the scope of the appended claims.
